摘要
为了调查我国新疆地区流产奶牛新孢子虫病和布氏杆菌病的感染情况，应用酶联免疫吸附试验（ELISA），对新疆15个地区419份奶牛血清样本（有流产史奶牛）进行了牛新孢子虫病和布氏杆菌病的检测。结果显示新疆地区流产奶牛新孢子虫感染率为10．3％，布氏杆菌病抗体阳性率为2．7％，同时检测到既有新孢子虫抗体又有布氏杆菌抗体的奶牛血清，占总数的0．95％，各牛场所检流产奶牛血清新孢子虫抗体阳性率在0—50％，各个年龄段奶牛血清的抗体阳性率差异不显著（P〉0．05）。不同妊娠胎次的奶牛血清抗体阳性率差异显著（P〈0．05）。调查结果表明，新疆部分地区奶牛存在新孢子虫的感染且是导致流产的重要原因之一。此次调查研究为今后新疆地区有效预防和治疗新孢子虫病提供了一定的科学依据。
The prevalence of Neospora caninum and brucellosis infections in dairy cattle in Xinjiang, China was investigated. The 419 serum samples taken from aborting dairy cattle 15 area, in Xinjiang were detacted for Neospora caninum and brucellosis infections by Enzyme Linked Immunosorbent assays （ELISA）. Of the 419 samples, 10.3 % and 2.7% samples were positive for N. caninum and Brucellosis infection, respectively. In addition, 0.95% samples were positive for both N. caninum and Brucellosis infection. The positive rate of all cattle farm Neospora caninum serum antibody - positive rate was 0 to 50% and there was no significant difference of the antibody - positive rate（ P 〉 0.05） between different ages of abortion cows sera, but they have significant difference （ P 〈 0.05 ） between antibody - positive rate of different times of pregnancy fetal cows sera. Survey results show that the Neospora caninum infections existence in some parts of Xinjiang and lead to abortion is one of the important reasons. The survey for the study provided scientific theoretical evidences for the effective prevention and treatment of cattle Neosporosis.
